R. w. MATTlsoN vALvE Filed Aug. 14; 1945 Y z5l Dec. 26, 1950 2mm' ne@am@ ATTORNEYS Patented Dec. 26, 1950 UNITED STATES PATENT OFFICE 1Claim.

An object of my invention is to provide a valve which includes a bodythat encloses a conipressible liquid-conveying tube. A concealed supportis carried by the body and contacts with the tube. A lever is pivoted tothe body and has a short arm adapted to bear against the tube at a pointopposite from where the tube contacts with the support. The lever has along arm that may be iranually moved when the body is vgrasped forswinging the short arm away from the tube and permit uid to flow throughthe tube. The long arm has a projection contacting with the tube thatwill be acted upon by the pressure of the fluid in the tube when thelone,r arm is freed and the pressure of the liquid in the tube in actingon the freed long arrn will cause the short arm to compress the tubeagainst the support and cut 01T the flow of liquid through the tube.

'The device is simple in construction and is durable and efficient forthe purpose intended.

ther obiects and advantages will appear in the following specication,and the novel features of the device will be particularly pointed out inthe appended claim.

My invention is illustrated in the accompany ing drawings forming a partof this application, in which:

Figure 1 is a vertical section through the device portions being shownin elevation;

Figure 2 is a side view of the device: and

Figure 3 is a horizontal section taken along the line 3-3 of Figure 1.

While I have shown only the preferred forms of my invention, it shouldbe understood that Various changes or modifications may be made withinthe scope of the appended claim without departing from the spirit andscope of the invention.

In carrying out my invention I provide a casing indicated generally atA. The casinar has a bore i therein for receiving a flexible waterconveying tube 2. The bore I communicates with a transversely extendingbore 3 and this bore has the water spray nozzle B mounted therein. Thenozzle has an inlet pipe 4 that receives the end of the tube 2. The piped has an annular rib 5 over which the tube is stretched and the tube endmay be secured in place by a band 5 or other suitable fastening means.

I will describe the construction of the nozzle B before describing theconstruction of the manually operable valve which controls the flow ofwater through the flexible tube 2. The body of the nozzle B iscvlindrical in shape and has a plug 'I screwed into one end and actingas a closure for this end. The plug has a reduced threaded portion 8 forreceiving a cap 9 and a washer I c is placed between the cap and thenozzle body. I ldo not wish to be conned to the exact structure forclosing the cylinder end since other closures may give the same results.

The other end of the nozzle B is closed except for a conicalnshapedopening I I through which water passes when a disc valve I2 is backedaway from the inner face I3 of the cylindrical body end. The valve I2 ismounted on a valve stem I4 and this stern is threaded at l5 so as to bereceived in a threaded bore I6 in the plug l. A reduced portion il ofthe ystem passes through a centrel opening in a washer I8 that is placedbetween the threaded portion 8 and the cap 9. A knurled knob I9 ismounted on the reduced stem portion I 'I and a turning of the knob willmove the face of the valve disc I2 toward or away from the inner surfaceI3 so as to control the amount of Water passing through the oriiice IIand also control the atomi'zation of the water. A iine or a coarse sprayis provided in this rranner.

The means for controlling the flow of water to the nozzle B comprises avalve lever C that is pivoted at 2.!! to the casing A. Figures 1 and 3show tbe upper end 2I of the lever as being wedge-shared in verticalsection and as having wide blunt end 22 that contacts with the tube 2 soas to compress it without cuttingr it. A wedge member 23 has a wideblunt edge 24 bearinfr against the opposite side of the tube and alignedwith the wide end 22. A hand screw 25 adiusts the position of the wedge23 toward or awav from the tube 2.

The opposite end of the lever C hasa buttonlike proiection 2S that bearsagainst the tube 2. The button 26 is disposed a greater distance fromthe pivot point 26 than the wide end 22 and therefore the lever effectproduced by the water pressure in the tube 2 on the button will cause itto swing the end 22 against the tube 2 and collapse it so that the tubewill be comu pressed between the end 22 and the edge 24. This will cutoff the ow of water to the nozzle B and constitute a valve. Should anyleakage occur when the handle C is freed, an adjustment oi the handscrew 25 will move the Wedge 23 toward the end 22 and tighten thepressure on the tube to cut off the ilow of water. The bore has aportion 21 disposed opposite the button 25 so as to prevent the tube 2from beingr moved out of alignment with the bore I by the pressure ofthe button thereagainst.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. v

When using the device, the hose 2 is connected to the house water faucetby any means, not shown. The valve lever C cooperates with the wedge 23to close the tube 2 so as to prevent water from entering the nozzle B.When the operator wishes to spray the clothes, he grasps the casing A inthe hand so that the exposed portion 28 of the lever C is received inthe palm I claim:

A valve for a clothes sprinkler comprising a body adapted to be graspedin one hand and enclosing a flexible tube connectible to a source ofwater supply under pressure, the body having an outlet communicatingwith the tube, an adjustable support concealed in the body and convtacting the tube, a hand lever pivotally `carried of the hand. The handis now moved to press;

the portion 28 against the palm and this will move the end 22 away fromthe tube 2 a distance sufficient to permit water to flow into the nozzleB under pressure. The water in issuing from the nozzle orice I I will beatomized and the coarseness or neness of the atomization is controlledby the adjustment of the knob I9.

The device willshut itself off automatically as soon as the lever C isreleased and this is accomplished without the use of a spring. Shouldany leakage occur, the hand screw 25 can be adjusted to overcome it. Thecasing A is made of a size and shape to be conveniently grasped by onehand. The same hand is used to depress the portion 28 of the lever valvefor turning on the water, thus leaving the other hand free to handle theclothes while they are being sprayed. The casing in actual practice maycomprise two halves held together by screws, not shown. This wouldpermit the casing to be opened and the nozzle B and tube 2 to be removedor inspected.

In actual practice, the conical opening II will have its inner end thatlies adjacent to the inner face I3, provided with a cylindrical borewhich is very short in length. At the'outer end of this bore and beforethe conical portion is reached, the oriice will have a shoulder or flatface that is perpendicular to the orice axis. The outer edge of the flatface is circular and merges into the conical portion of the openingwhich in turn extends to the outer end surface of the nozzle.

Should the conical opening extend all the way to the surface I3 withoutthe flat portion and the very thin cylindrical portion, an annoying dripwould take place at the nozzle. The construction just described avoidsthis drip. The conical opening I I permits the nozzle end to be thiol:to withstand the water pressure and still permit the water to be formedinto a spray.

by the body and having a short arm enclosed by the body whose end isdesigned to compress the tube against the concealed support for cuttingoif the water supply to the outlet, and a manually depressible long armwhose end bears against the tube, the water pressure exerting suflicientforce and the ratio of the lengths of the arms being such that a freeingof the long arm from manual depression by the same hand will permit itto move under the pressure of water and cause the short karm to pressthe tube against the support for cutting off the flow of water to theoutlet, and manually adjustable means for adjusting the support towardand away from the short arm to regulate the valve REFERENCES CITED Thefollowing references are of record in the fue of this patent:
